ATTACHMENT FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 477,151, dated J une14, 1892.

Application filed January 15, 1892. Serial No. 418,143. (No model.)

To @Z whom, it may concern:

.Be it known that l', CHARLES K. PIcKLEs, of the city of St. Louis, inthe State of Missouri, have invented a certain new and usefulImprovement in Attachments for Steam-l3oil ers, of which the followingis a full,clear, and exact description, reference being had to the'accompanying drawings, forming part of this specification.

My invention relates to certain features of novelty in that class ofattachments for steamboilers wherein a downdraft and a water-tube grateare combined, the object being to sirnplify the construction andfacilitate the ease with which the attachment can be applied andrepaired.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is an enlarged detail vertical trans verse section taken online I I, Fig. V. Fig. II is a similar View taken on line II II, Fig. V.Fig. IIIisadetail vertical section taken on line III III, Fig. IV. Fig.IV is a similar view taken on line IV IV, Fig. III. Fig. V is adetailvertical section through the setting of the boiler, showing part of theboiler and the at- Fig. VI is an enlarged Vertical section taken onlineVI VI, Fig. I. Figs. VII and VIII represent slight modifications inthe manner of forming the watertube sections and arranging thewater-tubes therein.

Referringr to the drawings, l represents the boiler, having the usualsetting 2.

3 represents the iire-boX, and et the aslrpit. The grate of the fire-boxis composed of watertubes*by preference a lower series of large tubes 5and an upper series of small tubes 0 being used. These tubes communicateat their inner ends with a large connect ing-pipe 7 and at their outerends with alarge connecting-pipe 8, the manifolds communieating With theboiler through vertical pipes 7 and 8f.

My invention relates particularly to the manner of connecting the pipesforming the grate to the manifolds.

9 represents hollow castings or sections iit ted on the pipe 8 andcommunicating with the interior of the pipe through openings l0. (SeeFigs. III and IV.)

1l represents copper or other suitable gaskets located between thesections El, so as to form tight joints between thenrto prevent theescape of water passing through the water-tubes of the grate and throughthe sections and manifolds. It will be observed that each section hasahub-like portion iittingthe manifold, and from which there is anextension, 6o into which the ends of the tubes 5 and 6 are fitted, andby preference the sections are so formed that each alternate one willreceive two of the tubes 5 and one of the tubes 6, while theintermediate ones receive one of the tubes 5 and two of the pipes (i, asshown in Fig. III. Any suitable number of these sections are used,according to the width of the fire-box, there being a sufficient numberof them employed to extend across the lire-box, 7o as shown in Figs. Iand II.

12 represents castings or sections located on the inner connecting-pipe'and into which the inner ends of the tubes 5 and 6 are fitted, as shownin Figs. I and VI. These sections l2 are the same and are arranged thesame on their manifold, with which they communicate, as the sections 9;but by preference the extensions of these sections dependin a downwardly direction instead of projecting in an 8o upwardly direction, asdo the sections 9, the object being to provide for the pipe Z beingabove the water-tubes, so as not to interfere with the draft of thefurnace, which is downwardly through the grate and up through a S5 space14 between the manifold and the bridgewall let of the furnace, asindicated by the arrows in Fig. V. rlhe inner ends of the tubes 5 and Gare screwed into the sections l2 after the sections are putin place outheir connect- 9o ing-pipe, the tubes being inserted through thesections 9, which have removable plugs l5 to permit the insertion of thetubes. After the tubes are screwed into the sections l2 their outer endsare expanded in the sections 9, as shown at 16, Fig. IV. It will thus beseen that when either of the tubes are burned out it can be easily andquickly removed and replaced by another, and in caso one of thesections'should burn out (there will be no danroo ger of theconnecting-.pipes burning out, for the reason that they are covered Vandprotected by the sections) one of the couplings 17, by which themanifolds are connected to the pipes 7a and 8, can be removed and theconnecting-:pipe drawn outV past the section, which it is desired toreplace, and when Ithe*` new section is inserted, the .connecting-pipe?forced back to its normal position, and the couplings again applied, sothat a `construe-. tion of this kind affords the best facilities, notonly for the rst building up or construction of the attachment, but alsofor repairing itin any part which is likely to need repair.

In Fig. VII, I have shown the extensions of f the sections 9 projectingin an inwardly ini stead ofa downwardlydirection,in which case the tubeswould be screwed into the sections; 9, the sections 12 being ypr@videdwith the re= movable plugs to rpeninirt the insertion ,of the l tubes,which would be flanged in thQ-Sections 12 after they are screwed finto:the sections 9. In Fig. VIII, Ihavesihown fthe sections-,prei videdeach with a single lateral `Wingffor sup- Q porting the tubes 6, and,ifdesired, `the sec tions may be formed so -as to lreceive .only'the`tubes 5,` the tubes -6 being omitted altogether. This would beaccomplished by simply leaving o the latter `extensions 118. (Shown inFig. VIII.)

I claim as my invention?- 1. In yan attachment for steam-boilers, Vthecombination of the manifolds .consisting of connecting-.pipes andindependent sections mounted on said connecting-pipes, with thefurnace-grate iconsisting of water-.t ubes sef cured to said sectionsandcommunicatingbe-g tween said manifolds, substantially as and for thepurpose set forth.

2. In `an attachment for steam-boilers, the:

combination Aof the manifolds consisting of the connecting.- pipes, theremovable independent sections mounted on said connecting-pipes, andopenings 10 in said pipes, with the furnace-grate consisting ofwater-tubes connected to said sections and forming communication betweenthe manifolds and suitable communications between the manifolds and theboiler, substantially as and for the purpose set forth.

3. In an attachment for steam-boilers, the combination of theconnecting-pipes, a numberof independent removable sections mounted onthe pipes and communicating therewith to form manifolds, water-tubesforming the vgrate of the furnace and fitting into said sections, andvertical pipesformingeommunica tion between the vmanifolds and theboiler, .the rfront manifold being located beneath the Watentubes andthe inner manifold fbeing located above fthe waterft-ubes, substantiallyas shown `and described.

4. In an attachment for steam-boilers, the combination .of theconnecting-pipes, removl able sections fitted on the connecting-pipestoform manifolds, vertical pipes jointed to the manifolds and forming acommunication between the manifolds Vand the boiler, and water-.tubesforming the grate of the furnace,

: said water-.tubes being screwed into the sections `of the innermanifold and expanded into the sections of the outer manifold, thesections .of said outer manifold being provided with removable plugs,all substantially as and for the purpose set forth.
